UNITED STATES ROBERT JOY, OF BROOKLYN, NEW YORK, ASSIGNOR TO AMERICANcan AND roun- DBY COMPANY, NEW YORK N. Y., A CORPORATION OENEW JERSEY.DOORFLOCKING DEVICE.

Application filed September 17, 1923. Serial No. 663,022.

To all whom it my camera: v Be it known that I, ROBERT W. JoY, residingat Brooklyn, county of Kings, State of New York, and being a citizen ofthe United- States, have invented. certain new and useful Improvementsin Door-Locking Devices, of which the following is a full,

clear, and exact description, such as will enable others skilled in theart to which it appertains to make and to use the same, reference beinghad to the accompanying 'drawings, which illustrate the preferred formof the invention, though it is to be understood that the invention isnot limited to the exact details of construction shown and described, asit is obvious that various modifications thereof within the scope of theclaims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a of a hopperv bottom dumping car equipped with a doorlocking means constructed in accordance with this invention, the doorbeing shown. locked. in the fully closed position; r

Figure 2 is a section taken on the line 2-2 of Figure 1;

Figure 3 is a fragmentary side elevation on a larger scale of the carshown in Figure '1 showing in full lines the door held in a partlyclosed position; and Figure 4 is-a central horizontal section throughthelatch housing, the latch being .shown in plan view. I It is an objectof this invention to provide an improved door latching meansparticularly for use with the dumping doors of It is also an object ofthis invention to provide an improved door latching means adapted toretain the doors in a partly closedposition as well as in a fully closedpositio p In the drawings the invention is shown applied to 'a dumplngcar having side sills 1-, side sheets'2, side posts 3, and hopperscomprising hopper side sheets 4 secured to the side. sills land sidesheets 2 by rivets '5 which unite the side sheets 2 and side sills 1..The hopperside sheets 4 are reinforced along the door openings by Z-bars7 secured to the hop-per side-sheets by rivets 8. The door openings inthe hoppers are closed by doors 9 secured to the car body by hinges 10,the hopper doors being reinfragmentary side elevation 'by the web 12 ofthe Z-bar l1 forced by Z-bars 11 having webs 12 and flanges 13 and 14,the Z-bars being secured to the doors 9 by rivets 15 which pass throughflanges 14. At their ends the 2-- bars 11 project beyond the doors 9 andthe flanges 14 and part of the webs 12 are cut away. To the doors 9rivets 16 secure brackets 17 to which pawls 18'are pivotally secured bypins 19. I

To the hopper sheets 4, rivets 20 secure latch housings 21 havingsubstantially U- shaped walls 22 formed integral with a connecting sidewall 23. Each housing 21 is also provided with a reinforcing orpartition wall 24, both the partition wall 24 and the side wall 23 beingprovided with bosses having openings in which is mounted a pin 25. Thepin 25is secured in position by the flange 26 on the boss 27 on the sidewall 23 when the latch housin 21 is secured to the hopper side sheet 4.Mounted on the pin 25 is a latch 28 comprising a shank portion 29 andanirregularly shaped head portion 30, the junction of the head portion 30and the shank 29 forming a shoulder 31 on the lower side of the shank 29and a curved portion 32 on the upper side of the shank. The head 30 hasa curved portion 33 and an angular portion which forms a shoulder 34 onthe upper portion of the head. The shank 29 is provided on its uppersurface with a lug 36 and upon its lower surface with a "lug 35, the lug35 being positioned on the shank so as to engage with the inner surfaceof the U-shaped wall 22 of the latch housing 21 and hold the latch 28 sothat the latch will be raised by the engagement of the curved portion 33as the door 9 1s swung towards closed position.

When the door is locked in closed position, as shown in'Fig. 1, theshoulder 31 on the latch 28 is in engagement with that portion of theflange 13 which projects beyond the side of the door 9, the shank 29rests upon the web 12 of the Z-bar 11 and the pawl 18 is in en agementwith the curved portion 32 of the s ank 29, the pawl 18 amuming thisosition through gravity and serving to ock the latch 28 in engagementwith the Z-bar 11 and hold the door 9 in the fully closed position. Torelease the door 9 the .pawl 18 will. be rotated in a clockwise dithelatch 28 to be raised from engagement the pawl 18 will engage with theouter end ofthe Z-bar at which time have traveled alon the upper surfaceof shown in Fig. 3 to the of the latch and as the door is movedinwardly, thefcurved surface 33 of the latch traveling over the web 12of the Z-bar 11, the pawl 18 will be moved along the latch 28 until itdrops in back of the shoulder 34. while the curved surface 33 stillrests upon the web 12, as shown in Fig. 3. The entagement of the pawl 18with the shoulder 34 of the'latch 28-will retain the door in a partlyclosed position and enable the operator to apply a means for forcing thedoor to the fully closed position. The door will then be forced'inwardlyfrom the position position shown in Fig. 1, the curved surface 33traveling. on the web 12 of the Z-bar 11 until the shoulder 31 of thelatch 28 drops in back of the Z-bar and in engagement with the flange 13the pawl 18 will the latch28 and will have dropped into enagement withthe curved portion 32 of the etch, as shown in Fig. 1, thus locking thelatch 28 in engagement with the Z-bar 11 and locking the door in thefully closed position..

' What is claimed is:

1. The combination of a door, a latch for said door, and a locking awlfor said latch adapted to engage said latch to holdv said door in partlyclosed position.

2.'The combinationof a door, alatch for said door adapted to hold saiddoor in full closed. position, and a pawl adapted to loci; said latch inengagement with said door, said pawl being adapted to engage said latchto hold said door in partly closed position.

3. The combination of a door, a latch for said door, and a locking awlfor said latch carried by said door, saith pawl being adapted to engagesaid latch upon the closing of the door to hold said door in partlyclosed position,

4. The combination of a door, a pawl carried by said door, and a latchfor said said door to hold ed by said door having a shoulder enga yclosed popawl to hold said door in part sition.

5. The combination of a door, a pivotally mounted latch having ashoulder adapted to engagesaid door to hold said'door in 'fully closedposition, and a locking pawl for said latch, said latch having anoppositely disposed shoulder engaged by said pawl to hold said door in apartly closed position.

6. The combination of a dumping door, a latch for said door having meansadapted to engage said door to hold said door in fully closed positionand a pawl carried by said door and operative to lock said latch whensaid door is fully closed, said pawl being adapted to engage said latchto hold sald door in a partly closed position.

7. The combination of a door, a latch for said door having means adaptedto engage said door to hold said door in fully closed position, a awloperative to lock said latch when said oor is fully closed, and means onsaid latch eng ed by said pawl to hold said door in a part y'closedposition, said pawl being adapted to move to locking position as saiddoor is moved to fully closed position.

8. The combination of a door, a latch for said door having means adaptedto engage said door in fully closed position, a locking pawl for saidlatch opcrative when said door is full closed, and means on saidlatchen'gaged y said pawl to hold said door in a part y closed position,

to travel along said latch to locking position as said door is .moved tofully closed position and said latch moved to door locking position; 9.The combination of a dumping door, a latch for said door having meansadapted to engage said doorto hold said door in fully closed positionand a pawl carried by said door and operative to lock said latch whensaid door is fully closed, said pawl being adapted to engage said latchto hold said door in a partly closed position.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
